TQ.ALL-WHOM IT MAY CONCERN:

Be it known that I, GEORGE S. WALKER, of Erie, in the county of Erie, and State of Pennsylvania, have invented a new and improved Stove-Drum; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

The object of this invention is to provide an improved radiating stove-drum.

It consists ofa hollow radiating cylinder or drum, made of sheet metal, and suitably arranged to he applied to a stove in any desired manner, and having pipe-connections, for receiving anddischarging the product of combustion, and provided with an internal apparatus, for conveying the said product around and exposing it to the shell of the drum, in a manner to extract the heat therefrom, as will be more fully described on reference .to the accompanying drawings, wherein- Figuro'l represents a central vertical elevation of my improved drum, and Figure 2 represents a top view, with the cover removed. Similar letters of rci'erencc indicate corresponding partsv v A represents the drum which is provided with a cover, 13, and pipe-connections G and D, and'with a door, E. F and F represent vertical triangnlar fines, open at the bas c, and rounded at the apex; and G renrcscnts a horizontal triangular diviqlingplate arranged between them. V

- The line F is arranged, as shown in fig 1, to receive the product of combustion, and deflect it towards the side H of the drum, causing it to pass up through the space 1-1 over the point I of the triangular plate G, where it comes in contact with the outside oi the flue F, which shuts-oil the direct passage to the pipe D, and compels it to pass down through the space X, and under the point L ofthe dividing-plate, in contact with the outside of the iiuc F, which forces it against the side M of the drum, and into the space N, through which it passes into the flue F,'and thence into the exhaust-pipe I), having passed entirely around the drum, and been exposed to all parts of the surface thereof, whereby the radiation of the heat is very greatly facilitated.

The time and dividing-plate may be made separately from the drum, and beset in at the top before the cover is secured.

I claim as new, and desire to secure by Letters Patcnt--- The arrangement, within the drum H, and with relation to each other, of the curved fire-plates F F, to direct the products of combustion in the described manner herein set forth and shown.
